If (x, 3) is the solution to the equation 4x+2y=22, then what is the value of x? Can you solve it for me so i can see how you did it?
a. 8
b. 6
c. 5
d. 4
plug 3 in for y
4x+2(3)=22
4x+6 =22
-6 -6
4x =16
-----------
4 4
x = 4
Final Answer D; x=4
hope this helped
Thanks a lot!
To find the value of x, we can substitute the given solution (x, 3) into the equation 4x + 2y = 22.
Substituting y = 3, we get:
4x + 2(3) = 22
4x + 6 = 22
Next, let's solve for x.
Subtract 6 from both sides of the equation:
4x + 6 - 6 = 22 - 6
4x = 16
Divide both sides of the equation by 4:
4x/4 = 16/4
x = 4
Therefore, the value of x is 4. So, the correct answer is d. 4.
